Could a tongue swab replace sputum tests for TB?

NCT ID NCT05941052

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

Every year, millions of people with tuberculosis (TB) go undiagnosed. This study tests new, faster diagnostic tools that use a simple tongue swab instead of the usual sputum sample. Researchers will enroll 1,350 adults with cough or TB risk factors to see how accurate these point-of-care tests are compared to standard lab cultures.

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

tongue swab-based molecular assays

What this could lead to

If successful, this could lead to quick, easy, and affordable TB tests that can be used at clinics or community sites, helping diagnose more people early.

What could go wrong

This is a diagnostic accuracy study, not a treatment trial. The tests may not be sensitive or specific enough to replace current methods, and results may vary across different populations.
